盖板性能要求
盖板性能要求
Performance requirements of cover plate
1、硬度要求。一定的表面硬度防止钻孔上表面毛刺,但太硬会磨损钻头;
1. Hardness requirements. Certain surface hardness prevents burrs on the surface of the drill hole, but too hard will wear the drill bit.
2、本身成分不含树脂,否则钻孔时将腻污孔;
2. There is no resin in its composition, otherwise it will be greasy and dirty when drilling.
3、要求导热系数大,能迅速将钻孔时产生的热量带走,降低钻头的温度;
3. Require high thermal conductivity, which can quickly take away the heat generated during drilling and reduce the temperature of the bit.
4、要有一定的刚性防止提钻时板材颤动,又要有一定弹性,当钻头下钻接触的瞬间立即变形,使钻头精确地对准被钻孔的位置,保证钻孔位置精确。
4. It is necessary to have certain rigidity to prevent the plate tremor and elasticity when lifting the drill. When the bit touches the bottom of the drill, it will deform immediately, so that the bit can accurately locate the drilled hole and ensure the accurate drilling position.
5、厚度与公框格护坡模具 箱体护坡模具 华尔街铜牛 电阻柜 接地电阻柜 电缆保护接地箱 隔离墩模具 化粪池模具差要求。不平整的表面将对钻孔造成影响。
5. Thickness and tolerance requirements. The uneven surface will affect the drilling
